What is mellanoxXstpRootPort?
This value identifies which physical port on this switch is currently serving as the root port for the spanning tree instance. An admin uses it to see the actual uplink path traffic takes toward the root bridge, which is critical when troubleshooting redundant-link failover or unexpected traffic paths. For example, if mellanoxXstpRootPort changes from port 24 to port 26 after a cable is pulled, that confirms spanning tree failed over to the backup uplink.
